| Abstract: | Molysite is introduced into releasing agent and with the increasing sensitivity of molysite,a method for determination of ultra trace gold in rock samples by graphite furnace atomic absorption spectrometry is introduced.Detction limit of the method is 0.02 ng/g with precision of 5%~8% RSD n=12.The method is accurate and reliable.Through the test of first grade national standard reference materials,the result meets the quality demand and is in agreement with certified values. |
